Transactions can fail for various reasons. The following are the most common:
1.Insufficient Card Balance:
-Before making a payment, ensure that your card has sufficient funds to cover the required amount.
2.Merchant Category Code (MCC) Risk:
-Some merchants' categorization codes are considered "high risk" by credit card institutions or issuing banks, which may result in your transaction being declined.
3.Network Connection Issues or System Failure:
-Check your network connection and retry the payment.
4.Incorrect Card CVV Input:
-Ensure that the security code you input is accurate.
5.Non-support for 3D Secure Verification on Virtual Cards:
-This might lead to the inability to complete transactions with certain specific merchants.
